China's petrochemical industry "12th Five-Year" energy-saving emission reduction is quite difficult

In respect of energy conservation, if the structural adjustment efforts are not enough, if high-energy-consuming industries operate at a high level and the proportion of the tertiary industry does not reach the expected target, then by shutting down a few small projects, energy-saving goals will be difficult to accomplish. On the one hand, China is in the middle of industrialization. Real estate, transportation and other infrastructure projects have great demand for steel and cement, and there is room for development in heavy chemical industry. On the other hand, due to local fiscal and political performance factors, all provinces are on industrial projects, the industrial concentration is not high enough, the elimination of backward production capacity is not enough, large and medium-sized SMEs have higher energy consumption and pollution control is more difficult. In the aspect of environmental protection, especially the reduction of nitrogen oxides, last year was the first year of the “Twelfth Five-Year Plan”. The design, research, and construction of many environmental protection projects will take a certain period of time. It will take only three years before the results can be seen. For example, coal-fired denitrification has both cost problems and technical problems. In recent years, car sales have increased significantly, and oil consumption has been rapid. This year's environmental protection situation is still not optimistic. The key is to lay a solid foundation and policies are in place. Only next year will the environmental protection situation be expected to improve.

Mountain Bike is designed for crosscountry (hills, path, plains and sand gravel road, etc.) ,born in 1977 in the United States on the west coast of San Francisco. At that time, a group of young people having fun on the hillside had an abrupt fantasy: "if I can ride a bicycle dashed down from the mountain, must be very interesting." Then they started to design the crosscountry bicycle. 2 years later , the mountain bike was officially named.
